Start with a Breakaway.
Note: This trick may require a less responsive yo-yo.

In one smooth motion take the
throw hand and make a sharp half circular movement in the direction
of the yo-yo. What this does is causes the string to come around your
wrist down towards the yo-yo. Bring your wrist close to the yo-yo to
help guide the string into the gap.

Dismount from the wrist hold by pushing into
the throwhand attached string with your non-throwhand. Return it to the
original position.

The second wrist whip is simply
making a single circle around the yo-yo, and then whipping the string
towards the gap. This is more of a flourish than anything and if done
smoothly can be very eye appealing.

Again dismount from the wrist hold by pushing
into the throwhand attached string with your non-throwhand. Return it
to the original position.

The third wrist whip is making two circular motions
before making the whipping motion. Again this is more of a flourish but
if done well looks
extremely
difficult...

Again dismount from the wrist hold by pushing
into the throwhand attached string with your non-throwhand. Return to
the hand.
